I have a 4 blade 24p bravo on there now, i get 65mph on gps and rpms 5200. It pops out of the hole very quick. Any advice on a better prop to get me closer to 70mph?

That was funny. Thanks for the laugh. LOL. 
Smiley face after a word or sentence is me joking.
Engine mods are helpful to know though. Right ? Of course they are.
I have already forwarded this to a group of Baja owners I know. Will let you know what they respond with, if they respond.

If boat has a 1.5 ratio drive you have 17% slip. Your motor has been modified with getting 5200, so might just need a tuned prop and reduce some trim. Boat is 3650 lb with 8.4 beam
My 4000 lb Rinker 232 cuddy (8.6 beam 300 hp 454) 1.5 drive hits 60 mph at about 4825 or so.

..........if you can only spin your current prop 5200 then you're pretty close
